Anti-UAW sign on digital billboard in Chattanooga area.
Workers assemble Volkswagen Passat sedans at the German automaker's plant in Chattanooga. Workers at Volkswagen's only U.S. factory will decide in February 2014 whether to be represented by the United Auto Workers union.
An anti-union message is visible Tuesday on a triple-flip billboard for northbound motorists on state Highway 153, between Shepherd Road and Shallowford Road.
The head of a group putting up 13 anti-United Auto Workers billboards in Chattanooga said Thursday the move focuses on the union's "economic legacy" in its home town of Detroit, which has filed for bankruptcy, and the UAW's "left-wing nature" of supporting President Barack Obama and other Democrats.
